PATENT OFFICE.

ELECTRIC WATER HEATER.

Application filed June 5, 1922. Serial No. 565,801.

To all whom it may concern.

Be it known that we, FREDRICK E. SHED ARD and JOHN E. PHILLIPS, citizens of the United States, residing at Tampa, in the county of Hillsborough, State of Florida, have invented a new and useful Electric Vater Heater; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to electric water heaters and has for its object to provide a device of this character comprising a porcelain body member having imbedded therein spaced carbons and water passages through the body between the carbons and a water passage through the bottom of the porcelain between the carbon, through which water will pass and circulate as it is heated by the carbon. Also to provide a simple water heating device which may be placed in a bucket oi: water or bath tub and the water quickly heated.

A further object is to so construct the device whereby when the same is out of the water the circuit will be opened and consequently the carbons will not be heated,

thereby obviating danger incident to fire.

\Vith the above and other objectsin view the invention resides in the combination and arrangement of parts as hereinafter set forth, shown in the drawings, described and claimed, it being understood that changes in the precise embodiment of the invention may be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawings Figure l is a side elevation of the heater, parts being broken away to better show the structure.

Figure :2 is a horizontal sectional view taken on line 2-2 of Figure 1.

Figure 3 is a bottom plan view.

Referring to the drawings, the numeral 1 designates a substantially cylindrical porcelain body of the device, which body is provided with a vertical transversely disposed opening 2 through which water flows. The bottom of the body member 1 is provided with an opening 3 through which water may pass to the opening 2. Imbedded in the por celain body member 1 at opposite sides of the opening 2 are semi'circular shaped car bons 4, which carbons have their flat sides 5 in registration with the opposite walls of the opening 2 where the water will contact therewith and be heated. The carbons 4. are preferably formed by severing a cylindrical piece of carbon longitudinally so as to form the two carbon sections 4 which, are semi-circular in horizontal. cross section. Theupper and lower ends of the carbon sections 4 terminate adjacent the ends of the body member 1, however they are spaced from the ends of the body member, thereby allowing the formation of a porcelain wall 6 between the ends of the carbon sections and the ends of the body member.

Imbedded at 7 in the upper ends of the carbon sections 4 and extending through the upper walls 6 are electric conductor members 8, to which may be attached electric wires by means of a plug or otherwise. When the current flows through the members 8 when the device is disposed in water the resistance oi the carbon members 4 will cause the carbon members to heat and the circuit will be completed through the water .within the opening 5. As the water heats within the opening 5 a circulation of the water will take place and the Water will be rapidly heated.

From the above it will be seen that a water heating device is provided which is simple in construction, the parts reduced to a minimum, and one which may be easily and quickly placed in water or removed therefrom.

The invention having been set forth what is claimed as new and'useiul is:-

1. An electric heater comprising a body memberformed from insulating material and having a transversely disposed opening extending therethrough, spaced carbon members imbedded in the body member, said spaced carbon members having their adjacent faces in registration with the opposite faces of the transversely disposed opening, and conductor members connected to the carbon members and extending through the wall of the body member.

2. An electric heater comprising a body member formed from porcelain and having a transversely disposed opening extending therethrough, spaced elongated carbon members imbedded in the body member and segmentally shaped in. horizontal cross section, the-fiat sides of the carbon members forming parts of the opposite walls of the transversely disposed opening and conductor members versely disposed opening, the upper ends of the carbon members extending above the upper end of the first mentioned opening, and conductor members imbedded in the upper ends of the carbon members and extendingthrough the Wall of the porcelain body member.

In testimony whereof We have signed our names to this specification in the presence of two subscribing WltDGSSGS;
